Create Questions

Quickly create sets of surveys to ask your participants. The ohmage platform was built for mobile data collection. It supports simple responses like multi-choice, text and numerical as well as responses with images, video and audio. User responses can automatically include passive data like the GPS location and time that the responses were taken.

Get Participants

Use our tool to create accounts and define a group for your participants. This tool can help you dynamically add and remove participants from your study as well! Parctipants can also create their own accounts, if that's preferred.

Collect Data

After you have launched your surveys, your participants can easily download your surveys on their android or iOS device and start participating. Surveys can even be completed while your participants are offline and uploaded later! You can even monitor their collection activities as they progress.

Android app on Google Play
iOS ohmageX app on App Store

Visualize/Analyze Data

You (and your participants) can visualize and analyze the collected data any time. ohmage provides different interactive tools (i.e. Interactive Dashboard and PlotApp) for you to explore your data. You can also easily export the data for your own statistical analysis.
